such as of the instantaneous type, one of t e objects being to provide a heater utilizing a plurality of coils all of the coils being connected at one end to a common receptacle and at the other end to a common receptacle, whereby a rapid and complete circulationof fluid through each coilis set up independently of the circulation through the other coils, this action resulting in a quicker heating of the fluid contents of the coils than would otherwise be possible and materially increasing the capacity of the heater.

' practically all of the heat A further object is to connect the coils to receptacles or headers so located that generated at the burner will be utilized in raising the temperature of the contents of the coils and receptacles.

With the foregoing and other objects in view .which will,appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes inthe precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without 'departing from the spirit of the invention.

In the accompanying drawings thepre ferred forms of the invention have been shown.

cated in the upper portion of the casing H may be arranged a thermostat indicated generally at This thermostat and the mechanism controlled thereby does .not constitute any part of the invention and has not, therefore, been shown or described in detail.-

T for controlling the flow of Arranged in the lower portion of the cas- I ing H is a ring-like header or receptacle 3.

A fluid conduit -1- opens into. this receptacle 3.while another fluid conduit 5 opens into the receptacle or header 1. Interposed between the two receptacles 1 and 3 is a circu lar series of coils 6. These coils are ar ranged in pairs, as shown particularly in Fig. 1, the coils of each pair being oppositely disposed so that the convolutions of the two coils will interfit. The lower convolutions of the coils of each pair are connected to the opposite ends of a T-fitting 7 mounted on and communicating with the receptacle 3. The said coils are similarly connected by T-fittings 8 to the upper re-- ceptacle or header 1. Thus fluid flowing from the receptacle T-fittings 7 will be divided into two streams flowing upwardly through the separate coils connected 'to the fittings and thence will enter the fitting S at the upper ends of the coils and flow into the header or receptacle 1,

In order that the space between the circular series of coils may be partly filled with additional coils, I wardly from the receptacle 3 to a-T-fitting 10 which is supported thereby at the center of the space surrounded by receptacle 3 into one of the' a pipe 9 is extended inwalls of the lower receptacle 3, or Withthe bottom'of the header or receptacle 1. result, the greater percentage of the heat will be utilized and better results will be obtained from the burning of a predetermined amount of fuel, than would otherwise be possible. As all of the coils open into commen receptacles at the top and bottom of the casing H, fluid will be drawn equally from all of the coils andthe capacity of the heater will bematerially increased.

Instead of providing separate receptacles intowhich the ends of the coils open, a con tinuous Water jacket l3 can be fitted snugly within the casing H and T-fittings M can be arranged within the water jacket at the ends'thereof, the ends of thecoils being attached to these fittings. pipes 15 can be extended inwardly from the ends of the jacket to the center of the space surrounded by said jacket and can be proyided with fittings 1G to which the central coils 17 are attached. With this arrangement of parts, all of the fluid heated within the coils is taken from and discharged .into the jacket -13.and the fluid fed to the heater is directed first into the jacket and is then withdrawn from the jacket. Consequently an ample supply of heated fluid is accessible at all times and this fluid will be drawn equally from all of the coils. In the forms shown in Figs. lto 3 inclusive, it will be seen that the upper receptacle or header 1 constitutes a batl'le whereby the greater per centage of heat passing above the coils 11 is absorbed by the contents of the header or receptacle 1. i

What is claimed is 1. A fluid heater including a ring-like fluid receptacle, a circular series of coils in COlIllHlll'llCiltlOIl with said receptacle, said coils being disposed in pairs, the coils of each pair interfitting, centrally disposed coils surrounded by said series of coils and communicating with the receptacle, all of the coils overhanging the opening surrounded by the receptacle.

2. A fluid heater including ring-like fluid receptacle having a space therethrough Furthermore the for thepassage of hot products of combustion, a circular series of coils connected to the receptacle, said coils being arranged in pairs, the coils of each pair interfitting, a coil supported at the center of the space surrounded by the receptacle and connnunicating with the receptacle, and means for directing fluid to and from the receptacle and coils.

3. A fluid heater including a fluid receptacle having a space extending therethrough for the passage of hot products of combustion, a circular series of coils communicatin with the receptacle, said coils being arranged in pairs, the coils of each pair intcr fitting, a central coil communicating with the receptacle and surrounded by said circular series of coils, all of the coils overhanging the space. for direct contact with the hot products of combustion flowing through the space.

4:. A fluid heater including a casing, a fluid receptacle in the upper portion thereof and having Vent openings therethrough for products of combustion, a. ring-like fluid receptacle in the lower portion of the casing, a circular series of coils interposed between and connnunicating with the receptacles, said coils being arranged in pairs, the coils of each pair interfitting, and a coilintcrposed between the receptacles and surrounded by said circular series of coils, all of said coils o\'*erhanging the space surrounded. by the ring-like receptacle and all of the coils communicating with both the receptacles.

In testimony that I claim the foregoing as my own, I hare hereto afiixed my signature in the presence of two witnesses.
